More aware and cautious of what I buy / subscribe too. Cancelled all american run online stuff (amazon, netflix, etc.). Joined CBC Gem (and pay a subscription) in the hopes that maybe more content can be created. I also avoid American websites as much as it's reasonably possible; which is kind of easy for me anyway since I don't surf much anyway.
So, I pretty much only look to buy and participate in Canadian only stuff and European stuff.
Just a simple little nitpick:
On the Nix/NixOS section of install, you type
nix-shell -p managarr works just fine on NixOS proper. I use it all the time.
